Embodiment Construction

[0015] The specific embodiment of the present invention is as follows.

[0016] figure 1 Shown is the framework diagram of the regional power grid. In the regional power grid, the power supply includes external input power, as well as distributed power sources, such as photovoltaic power plants, wind power plants, etc.; in terms of load, it includes conventional loads, micro-grids, and electric vehicle charging piles. and energy storage systems.

[0017] In this embodiment, one hour is used as a time interval to calculate and obtain the carbon emission intensity data of the current load node and compare it with the threshold data.

[0018] When the data is higher than the threshold value, it is judged that the power supply of the current node system is high-carbon electricity, and the current node load uses as little electricity as possible for the purpose of control. If the current load includes conventional interruptible loads, it will be interrupted without affecting norma...

Abstract

The invention relates to a carbon-emission-analysis-combination-based diversified load control method. The method comprises: according to a result of comparison between current load node carbon emission intensity data obtained by calculation and threshold data, difference controlling is carried out on loads with different types; when the current load node carbon emission intensity data obtained by calculation are higher than the threshold data, power supply of a current node system is determined to be in a high carbon power mode and thus a control goal of minimizing power usage by a current node load is set; and when the current load node carbon emission intensity data obtained by calculation are lower than the threshold data, power supplying of the current node system is determined to be in a low carbon power mode, and thus a control goal of increasing power usage by the current node load is set. According to the invention, the carbon emission calculation result is associated with the load control; and controllable characteristics of loads with different types are taken into consideration fully. Therefore, the power consumption way can be adjusted reasonably according to the carbon emission situation of the power grid and thus an objective of carbon emission reduction of the power grid can be achieved.

Description

[0001] technical field [0002] The invention relates to a diversified load control method combined with carbon emission analysis, which belongs to the technical field of energy saving and emission reduction. Background technique [0003] With the development of industry and the deterioration of the environment, energy conservation and emission reduction has increasingly become the focus of attention, among which the realization of low-carbon control and operation of the power grid is an effective means of energy conservation and emission reduction. At present, there are many R&D and applications of power grid optimization control technology including distributed power generation. The main focus is the consumption of new energy and power grid loss reduction, and it is not directly related to carbon emissions. In recent years, based on the carbon emission flow theory, the carbon emission intensity of any line and node can be calculated in real time based on the grid power flo...
